Crises are negative changes in the human or environmental affairs, especially when they occur abruptly, with little or no warning. More loosely, a crisis is a testing time for an emergency.

Overaccumulation is one of the potential causes of the crisis of capital accumulation. In crisis theory, a crisis of capital occurs due to what Karl Marx refers to as the internal contradictions inherent in the capitalist system which result in the reconfiguration of production. The contradiction in this situation is realized because of the condition of capitalism that requires the accumulation of capital through the continual reinvestment of surplus value.

A polycrisis (from the French polycrise) is a situation in which multiple, distinct crises (economic, environmental, geopolitical, social, or technological) occur simultaneously and interact in ways that amplify each other, producing outcomes more severe than the sum of the individual crises. The concept highlights the interdependencies and feedback loops between global systems, where shocks in one domain (e.g., climate change, financial instability, pandemics, energy insecurity, or political conflict) cascade into others.
